This is the legal name of the company or business operator which provides the service under the trading name.

The Company Group is the parent company which owns the service provider. Often one larger group owns many brands which may operate as separate businesses, but owned by the larger group.

ISPA is the Internet Services Providers' Association (www.ispa.org.uk), a trade association which many ISPs are members of. ISPA members are subject to the ISPA Code of Practice in addition to any other dispute resolution schemes they may subscribe to.

The Ofcom Voluntary Code of Practice (Broadband) is an agreement broadband providers can subscribe to which promises they will provide consumers with information on the speeds they can achieve, what sort of traffic limits might be in place, etc. More details at www.ofcom.org.uk

Migration is the process of moving a broadband service from one ISP to another, usually minimising the amount of disruption in the process. Inbound migration means your ISP will allow you to transfer to their service from another ISP. Outbound migration means you can transfer from their service to another ISP.

If your ISP doesn't support migration, you would need to cancel your broadband service, wait until it's removed from your line and then re-order with another ISP. This may cost most and will result in a longer period of no connectivity.

We recommend you choose an ISP which support both inbound and outbound migration.
